NTC/362
Introduction
Kudler Fine Foods has established that they want to design a WAN to tie three different locations together and make the internal network in each store a Wireless Local Area Network. Then, they are requesting Voice Over Internet Protocol to each multi store network. Various protocols make all this happen. Transfer Control Protocol and Internet Protocol are the foundation of data transfer. TCP is the protocol that the internet, email and ftp highly rely on. Without TCP/IP there would be no internet, email or FTP. Two other protocols designed to process packets throughout the network are X.25 and Frame Relay. For this scenario Frame Relay will be used so I will not provide a brief description about X.25. Frame relay was based on the X.25 protocol and even though the option isn’t there to check an error, which is the end stations responsibility. Frame relay does reduce the amount of overhead associated with data transmission, which allows for a faster packet switching method. As recommended this network will use a T1 line to reach the required bandwidth from node to node. This will give the customer the option to data burst the line. However, if the network traffic is heavily congested it will be controlled so everyone is satisfied. Frame relay uses a specific fast packet switching technology that allows overhead reduction. Flow control and error correction determines the efficiency of the fast packet switch. Now what happens is the frame relay inside the network will detect the error and simply just drop the frame.The OSI model divides network communication into seven layers. Each layer describes the various protocols and function. Using Frame Relay you now get to exclude any layer 3 protocol because the operation is performed on the second OSI layer (data-link).When the company adapts a fully connected topology will be used. As for right now, the setup will resemble a Ring Topology.
